Accessing the radgrid values in codebehind while Editing

hi All,

I have a dropdown (programgroup) in my edit form for which I want to set the selectedvalue in the code behind and not in aspx. For that I have to know the value that is in the radgrid cell for that column. Please see the code below. I have a different datakey and this program group cannot be the datakey.

This is my aspx definition:
In MasterTable View:
<telerik:GridBoundColumn UniqueName="ProgramGroup" HeaderText="Program Group" DataField="ProgramGroup" DefaultInsertValue=""> </telerik:GridBoundColumn>

In the EditForm Template:
<asp:DropDownList ID = "ddlProgramGroup" runat = "server" TabIndex="8" Width="200px" DataTextField = "List_Item" DataValueField = "List_Value" DataSource ="<%# dsProgramGroup(true) %>" >
</asp:DropDownList>

In the CodeBehind:
Private Sub rgSearchResults_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles rgSearchResults.ItemDataBound
If TypeOf e.Item Is GridEditFormItem And e.Item.IsInEditMode Then
Dim item As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
Dim ddlDropDownList As DropDownList = DirectCast(e.Item.FindControl("ddlProgramGroup"), DropDownList)
If Not IsNothing(ddlDropDownList) Then
Dim strPrg As String = "VALUE IN THE RADGRID CELL"
ddlDropDownList.Items.FindByText(strPrg).Selected = True
End If
End If
End Sub

Is there a way to find out the value of the program group is the radgrid_ItemDataBound event

Group Footers Showing When They Shouldn't

This has been driving me nuts for the past couple days. I have a grid that has a customized GroupFooterTemplate. There's three different levels of grouping (this doesn't seem to happen with just two). GroupLoadMode is set to Client, ShowGroupFooter is set to True, GroupsDefaultExpanded False, and RetainGroupFooterVisibility is True.

When the grid is initially displayed, all top level groups are shown collapsed with their group footers as expected. When I expand a top level group, the first second-level group is displayed with it's group footer, but the second second-level group is also showing a third-level group footer. If I expand and collapse that second-level group, it is now displayed correctly.

If I change the GroupLoadMode to Server, it works as expected. If I only have two levels of groups, it works as expected. Am I doing something wrong or is this a bug? I'm using version 2012.2.912.35

I've attached a picture showing what it looks like. In the group footer, I'm displaying the group index. As you can see, under "Segment 1"->"Group 2", there's three footers. The 0_2_2 shouldn't be there as that is from a group inside of "Group 2".

Hierarchical grid - columns in inner-grid refusing to resize

The subject pretty much says all. I can't seem to find any way to get the columns in the inner-grid of a two-level hierarchical RadGrid to resize. Below is the code I'm attempting:

ASPX:

<telerik:RadGrid ID="XLSView" runat="server" AutoGenerateColumns="True" AllowMultiRowSelection="true" Width="600px">

<MasterTableView Width="100%">

<DetailTables>

<telerik:GridTableView Width="100%">

<Columns>

<telerik:GridTemplateColumn UniqueName="chkDup" HeaderText="Select">

<ItemTemplate>

<asp:CheckBox ID="chkDup" runat="server">

</asp:CheckBox>

</ItemTemplate>

<HeaderStyle Width="200px" />

</telerik:GridTemplateColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

</MasterTableView>

<ClientSettings>

<Scrolling AllowScroll="true" />

</ClientSettings>

</telerik:RadGrid>

VB:

Protected Sub XLSView_DetailTableDataBind(sender As Object, e As Telerik.Web.UI.GridDetailTableDataBindEventArgs) Handles XLSView.DetailTableDataBind

...

Dim test As DataTable = New DataTable()

test.Columns.Add("FileID")

...

For Each dupFile As FILE In dupFiles

Dim dr As DataRow = test.NewRow()

dr("FileID") = dupFile.FILEID

...

Next

e.DetailTableView.DataSource = test

------------------------------------

Protected Sub XLSView_ColumnCreated(sender As Object, e As Telerik.Web.UI.GridColumnCreatedEventArgs) Handles XLSView.ColumnCreated

If e.Column.UniqueName = "Description" Then

Dim boundColumn As GridBoundColumn = CType(e.Column, GridBoundColumn)

boundColumn.HeaderText = "DescriptionA"

boundColumn.ItemStyle.Width = 600

boundColumn.HeaderStyle.Width = 600

boundColumn.FooterStyle.Width = 600

boundColumn.FilterControlWidth = 600

End If

End Sub

I get a good hierarchial grid, with the only exception being that the column of checkboxes that's in the ASPX will not widen and the numerous column resize attempts in the ColumnCreated function(which DOES fire correctly; the HeaderText property does change to "DescriptionA") also will not widen. Can anybody please tell me what I'm doing wrong?

Thank you for any help you may have in advance.

RadTreeViewContextMenu in a TreeView within a RadMenu - Context Menu doesn't display in Chrome

Hi,

I am using 2012.3.1016.35 of the ASP.NET for AJAX controls.

I have a RadMenu containing a RadMenuItem, which contains a user control that contains a RadTreeView. The RadTreeView uses a RadTreeViewContextMenu on the nodes.

In IE and Firefox, the Context Menu displays as expected, AFTER I set the z-index of the RadTreeViewContextMenu as follows:

style="z-index:40000"

PROBLEM:
The context menu does NOT display in the latest version of Chrome (version 22.0.1229.94, but I assume it is also a problem in earlier versions).

This is a huge deal for us. I've seen one other forum post on this, where Telerik simply says it "looks like a documented bug in Chrome".

MORE INFO:
I use the exact same type of treeview and context menu in two other places of our web app, but in those places I do NOT nest the treeview in a radmenu, and in those cases, the context menu DOES DISPLAY in Chrome.

Can you help please? Is there anything I can try, to get this to work?

Thanks,
Brent

RadPanelBar ItemClick does not fire when expand/collapse icon is clicked

I am trying to implement Load On Demand for the RadPanelBar. If I click on the Expand/Collapse button the ItemClick never fires. Also when another item is expanded, then the control that was previously loaded dissapears. I have been trying to make this work for over a day.

<form id="form1" runat="server">

<div>

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<telerik:RadAjaxManager runat="server" ID="RadAjaxManager1">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadPanelBar1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadPanelBar1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadPanelBar ID="RadPanelBar1" runat="server" OnItemClick="RadPanelBar1_ItemClick"

ExpandMode="MultipleExpandedItems">

<CollapseAnimation Duration="100" Type="None" />

<Items>

<telerik:RadPanelItem runat="server" Text="Root RadPanelItem1">

<Items>

<telerik:RadPanelItem runat="server">

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

<telerik:RadPanelItem runat="server" Text="Root RadPanelItem2">

<Items>

<telerik:RadPanelItem runat="server">

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

</Items>

<ExpandAnimation Duration="100" Type="None" />

</telerik:RadPanelBar>

</div>

</form>

public partial class RadPanelBarTest : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

private void LoadUserControl(Telerik.Web.UI.RadPanelItem item)

{

Label userControl1 = new Label();

userControl1.ID = "userControl1";

userControl1.Text = DateTime.Now.ToString();

item.Items[0].Controls.Add(userControl1);

item.Expanded = true;

}

protected void RadPanelBar1_ItemClick(object sender, Telerik.Web.UI.RadPanelBarEventArgs e)

{

this.LoadUserControl(e.Item);

}

I basically used the exact suggestion here: http://www.telerik.com/community/forums/aspnet-ajax/panelbar/radpanelbar-with-load-on-demand-items.aspx , except i changed the ExpandMode to multiple and i used a label for simplicity of this post.

Client performance

I have been having problems with the self hierarchy with the RadGrid control with the columns not lining up. It is a cross-IE problem. I decided to look at the TreeList control. How can I have all of the data on the client pre-loaded without having to make a server call for each expand/collapse.
